Question

Dilute 0.407M & 2.56L solution to 7.005L. CF?

0.149M

0.898M

44.1M

1.11M

Answer 1

C₂ = 0.149 M

Step-by-step explanation:

Given data:

Initial concentration = 0.407 M

Initial volume = 2.56 L

Final volume = 7.005 L

Final concentration = ?

Solution:

Formula:

C₁V₁ = C₂V₂

C₁ = Initial concentration

V₁ = Initial volume

C₂ = Final concentration

V₂ =Final volume

Now we will put the values.

0.407 M × 2.56 L = C₂ × 7.005 L

1.042 = C₂ × 7.005 L

C₂ = 1.042 M.L / 7.005 L

C₂ = 0.149 M
